1、2015淄博市淄博市高考英语阅读理解一轮基础练习（2）答案阅读理解-科普知识类阅读下列四篇短文，从每小题后所给的 A,B,C 或 D 四个选项中，选出最佳选项。(2013福州质检)Lets face it.No one drinks diet sodas for the taste.People drink diet sodas in the hope that it will help them lose weight or at least keep them from gaining it.Yet it seems to have exactly the opposite effect，
2、according to a new study.Researchers from the University of Texas said those who drank two or more diet sodas a day had waist size increases that were six times greater than those who didnt drink diet sodas.“What we saw was that the more diet sodas a person drank，the more weight they were likely to
3、gain， ”said Sharon Fowler.The study was based on data from 474 participants in a large，ongoing research project，where the participants were followed for nearly 10 years.While the findings are surprising，they also offer some explanations.Nutrition expert，Melanie Rogers，who works with overweight patie
4、nts in New York，has found that when patients are switched from regular to diet sodas，they dont lose weight at all.“We werent seeing weight loss necessarily，and that was confusing to us， ”said Rogers.So why would diet soda cause weight gain？No one knows for sure yet，but it could be that people think
5、they can eat more if they drink diet sodas，and so overcompensate for the missing calories.A related study found some sweeteners(甜味剂)raised blood sugar levels in some mice.“Data from this and other potential studies suggest that the promotion of diet sodas and artificial sweeteners may be risky.”said
6、 Helen PHazuda，professor at the University of Texass school of medicine.“They may be free of calories，but not of consequences.”【语篇解读】 一项新的研究表明，喝低糖汽水非但不能减轻体重，反而会使体重增加。1People drink diet sodas to _. Aenjoy its taste Bstay in fashionCachieve weight loss Dgain more energy解析 细节理解题。根据第一段中的“People drink di
7、et sodas in the hope that it will help them lose weight.”可知。答案 C2The new study suggests that drinking diet sodas _.Acauses people to become heavierBhelps people to be healthierCmakes people much thinnerDoffers people more calories解析 细节理解题。根据第一段的最后一句可知，新的研究表明喝低糖汽水非但不能减轻体重，反而会让体重增加。答案 A3We can learn f
8、rom the passage that _.Aregular sodas make people lose more weightBdiet soda drinkers tend to eat more foodCdiet sodas do help reduce caloriesDmost blood diseases come from diet sodas解析 推理判断题。根据倒数第二段中的“.they can eat more if they drink diet sodas.”可知，喝低糖汽水的人趋向于吃更多的食物。答案 B4The underlined word“They”in
9、the last paragraph probably refers to “_”AsweetenersBdiet sodas and artificial sweetenersCsodasDdiet soda drinkers and sweetener takers解析 词义猜测题。此处是承接上一句中的内容，故“They”指的是“低糖汽水和人造甜味剂”。答案 B【2014 高考英语广东省华侨中学四模高考英语广东省华侨中学四模】DA team of engineers at Harvard University has been inspired by Nature to create th
10、e first robotic fly. The mechanical fly has become a platform for a series of new high-tech integrated systems. Designed to do what a fly does naturally, the tiny machine is the size of a fat housefly. Its mini wings allow it to stay in the air and perform controlled flight tasks.“Its extremely impo
11、rtant for us to think about this as a whole system and not just the sum of a bunch of individual components (元件),” said Robert Wood, the Harvard engineering professor who has been working on the robotic fly project for over a decade. A few years ago, his team got the go-ahead to start piecing togeth
12、er the components. “The added difficulty with a project like this is that actually none of those components are off the shelf and so we have to develop them all on our own,” he said.They engineered a series of systems to start and drive the robotic fly. “The seemingly simple system which just moves
13、the wings has a number of interdependencies on the individual components, each of which individually has to perform well, but then has to be matched well to everything its connected to,” said Wood. The flight device was built into a set of power, computation, sensing and control systems. Wood says t
14、he success of the project proves that the flying robot with these tiny components can be built and manufactured.While this first robotic flyer is linked to a small, off-board power source, the goal is eventually to equip it with a built-in power source, so that it might someday perform data-gatherin
15、g work at rescue sites, in farmers fields or on the battlefield. “Basically it should be able to take off, land and fly around,” he said.Wood says the design offers a new way to study flight mechanics and control at insect-scale. Yet, the power, sensing and computation technologies on board could ha
16、ve much broader applications. “You can start thinking about using them to answer open scientific questions, you know, to study biology in ways that would be difficult with the animals, but using these robots instead,” he said. “So there are a lot of technologies and open interesting scientific questions that are really what drives us on a day to day basis.”41. The robotic fly project has been conducted _
